The fourth step for projects in the Back End is for teams to undertake the...

GInI’sCInP Handbookdefines the Back End’s fourth step as finalizing the design, where for products, engineering ensures the design is "consistently manufacturable" and meets the "Design and Innovation Intents" (specific value or experience goals set earlier). Consistency ensures scalable production, while intents tie back to the original vision (e.g., usability, performance). Option A, "manufacturing ready," is vague and customer satisfaction is an outcome, not intent. Option B, "easy to manufacture," lowers the bar—GInI seeks consistency, not ease—and "very happy" is subjective. Option D, "within quality limits," is close but "specifications" is broader than intents, which are strategic. Option C matches GInI’s exact wording and focus, aligning with the original answer, emphasizing fidelity to the innovation’s purpose through robust engineering—a critical Back End discipline.
